Abstract (en)
In an ultrasound receive beamformer signals from two or more aperture elements are multiplexed at the input of each beamformer channel, stored in different portions of a delay memory, delayed and apodized in a time-multiplexed fashion, demultiplexed at the output of the channel, and summed in different summation units running at an upsampled rate. The partial sums are then time-aligned, summed to produce the total upsampled beam sum, filtered and decimated in an interpolation filter to produce the beamformed signal.
